Remove opaque-frame-only code to reduce top resize border size by 1 px.

The stated goal of this was to make dragging the window easier (viz., by
increasing the size of drag area atop the window by 1 px).  However, this
changed the area size from 12 px. high to 13 px., which seems like a rather
trivial "improvement" to make, and we've gotten by without such a change in the
glass frame (which uses 12 px.) for years.  Furthermore, the top resize border
was changed from 4 px. to 3 px., which seems honestly pretty small, especially
when the glass frame will end up using Windows' default 8 px. or whatever.  So
remove this code to make the two frames match up better.
